From HM Revenue & Customs · Employment Income Manual
Section 36(1)(b) CAA 2001
The phrase 'necessarily provided for use in the performance of the duties' in the capital allowance legislation imposes the same objective test as that in the general rule for employees’ expenses in section 336 ITEPA 2003 (see EIM31640 and EIM31645).

Note that the plant or machinery does not have to be 'wholly and exclusively' used for the performance of the duties. If there is private use the allowances can be apportioned (see EIM36570).
